Network Monitoring

From Bandipedia

As much as we'd all like to, we simply can not personally keep an eye on our network infrastructure 24 hours a day. This is where automated network monitoring comes in. Automated Network Monitoring is more than just a simple program that pings your equipment every few minutes and alerts you when one of those pings drops. While ping or ICMP is one component of network monitoring there are many other health statistics that should be monitored in order to prevent a catastrophic event. Some examples include:

1. Bandwidth utilization or throughput.
2. CPU utilization of routers, switches and firewalls.
3. Memory utilization of routers, switches and firewalls.
4. Interface errors and discards.
5. Syslog and SNMP traps.


All of these metrics can be monitored and alerted upon based on thresholds that you define. when used together these metrics can be a powerful tool to help avoid a catastrophic event such as network down time. When developing a network monitoring strategy, one should consider these and other vendor specific metrics as key indicators to the health and status of your network.
